JACOB CAESAR, OF PERTH AMBOY, NEW JERSEY.

WINDOW.

SPECIFICATION forming part of Letters Fatent N 0. 676,352, dated June11, 1901.

Application filed October 25, 1900. Serial .No. 34,251. (No model.)

To (LZZ whom it may concern.-

Be it known that I, JACOB CAESAR, a citizen of the United States,residing at Perth Amboy, in the county of Middlesex and State of NewJersey, have invented a new and useful'Window, of which the following isa specification.

My invention relates to windows, and has for its object to provide awindow-sash which can be easily removed for the purpose of cleaningorglazing and at the same time provide a sash which will exclude thecold. I attain these objects by the construction illustrated in theaccompanying drawings, in which Figure 1 is aview of a window-sashconstructed according to my invention,'a part being broken away to showthe construction. Fig. 2 is a transverse vertical section of the upperpart of a window-frame adapted to my improved construction and also ofthe upper and a part of the lower sash, and Fig. 3 is a view of amodified form of construction.

In the accompanying drawings the several parts of myimproved sash andframe are indicated by numerals of reference, and in the practice of myinvention I provide a rectangular frame 5, which is constructedexteriorly substantially the same as an ordinary windew-sash and maybesuspended in a windowframe by means of the sash-cords 6 6. Within theframe 5 I mount a removable sash 7, containing the glass 8.

In order that the sash 7 maybe held in the frame 5 in a secure mannerand at the same time a tight joint be formed between them, so that thecold will not be admitted, I have provided the following construction:Small studs 9 are mounted in the bottom of the sash 7 and engage sockets10 in the frame 5, while a catch 11 at the top engages the upper end ofthe sash and, with the studs 9, serves to hold the sash 7 securely inthe frame 5 in a manner perfectly secure, but so that it can be easilyremoved, and by beveling the edges of the sash 8 and interior walls ofthe frame 5, as indicated by dotted lines in Fig. 1, a perfectly tightjoint will be formed, so that the cold and rain will be excluded, and Ialso provide a weather-strip 12 as additional means to prevent theadmission of the cold. It will thus be seen that by making the sashremovable, instead of pivoting or hinging the same to the frame 5, I amable to have the sides beveled in such a manner that the water cannotbeat in, as the beveling at the bottom of the sash will be downward andoutward, while the top and sides will be beveled so that the sash maymove inward when the catch 11 is unfastened. At the same timethe-beveling at the top and sides will form aseat for the sash, whichwill be further strengthened by the opposite beveling at the bottom, sothat the sash will set in the frame without placing much stress on thecatch 11 or studs 9, and the weight of the sash itself will increase thetightness of the joints, especially at the bottom and sides.

Instead of beveling the sides, as shown in Figs. 1 and 2, I may step thesash and frame together, as shown in Fig. 3; but the several stepsshould be beveled, as shown in the drawings.

In order that the upper sash may be removed at the bottom of the frame,provision should be made in the window-frame for raising the lower sashto a greater height than the upper sash is normally held, and this canbe accomplished by providing the windowframe 13 with a pocket 14: overthe lower sash, so that when the lower sash is raised the upper sashwill be easily removablej'as-willJoe readily understood.

In operation the sash is removed from the frame 5 and may be placed overa bucket of water and cleansed, thus avoiding the necessity of cleaningthe sash in the frame and the spilling of Water on carpets or the frame.Further, by the construction of the frame both sash may be removed atthe bottom of the frame, so that each can be easily handled and the coldcan be more readily excluded than in cases where the window-sash arehinged or pivoted.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A window comprising an upper and a lower sash, each of which consists ofa sliding frame having an aperture the lower wall of which is beveledoutward and the side walls and top inward, said frame being providedwith sockets communicating withsaid bottom wall, a sash, having theedges thereof beveled to correspond with said aperture,mounted therein,studs on the bottom of the last-named sash adapted to engage saidsockets, weatherstrips mounted between the said beveled walls and edges,and a pocket,as 14, formed in the window-frame above the lower sash, asand for the purpose set forth.

In testimony whereof have signed my name to this specification in thepresence of two subscribing Witnesses.

. JACOB CAESAR.
